Hey y'all I have an intersting 1972 Lincoln Cent and when I compare it to the types of Die for the 1972 it looks close to Die 04 for the Doubled. I have provided plenty of pics so please take a look. The Date seems doubled especially "72" . Also "Liberty" seems very Doubled especially the "L" and "Berty". Also the Reverse seems like a great example of DDR. Especially in the Motto and corners of Memorial.
Looks like MDD on the obverse and reverse to me...note the R in TRUST and the corner of the Memorial. Larry Nienaber
